hi all, i need to simulate several kinds of applications, such as skype, games, emule, video, audio etc. my question is how can i simulate these kinds of applications by the traffic trace file? should i sniffer the packet deliver time and packet size and record them in my own traffic

[ns] Flooding troubles

Hi, I am trying a wireless flooding scenario. The basic idea is that one node broadcasts to all nodes in its transmission range and every receiving node immediately retransmits the packet. I modified the wireless-flooding.tcl in /ns/tcl/ex for my needs but still get some irritating results:

Re: [ns] what is the differences between these bandwidth_s and rate_s?

Also I am asked why you use this complicated tcl parameters. NS, by default, has the data rate for the MAC set at 2 Mbps. But cards are faster now. My cards are 802.11b, which means they're 11 Mbps, and so we need to change this. Add the following to the beginning of your simulation script:

[ns] Assign a specific node id from tcl script

Hi all, I am currently trying to assign a specific node id to each node created in my tcl script but I can't find how to do it. When a node is created, tcl assigns a node id by incrementing its value with each new node, the C++ address is mapped on this node id I think. But in my case I don't

[ns] Change trace file during simulation?

Hi all, This is my first message on this mailing list. The trace file generated in my simulation is huge and I decided to parse it using awk during the simulation and delete it from time to time. I managed to run awk on the file, but the problem is that I can't change the trace file of the
